To an cv/mm it concern: Be 1t known'that I, EDWARD Jones, a citizen theUnited States, residing at Great Neck,,in the county of Nassau and Stateof New York, have invented new and useful Improvements in Demountahlelitims, of which the following is a specification.

The general object of this invention is to refine the construction ofvehicle wheels in point of providing a demountzible' rim for the same sothat -he vehicle tire which is secured to the said rim may be readilyremoved and re' laced in a. much more convenient and e" icient mannerthan has heretofore been done. And to these ends the invention consistsof e wheel having e fixed rim provided with a series of sockets arrangedon its periphery and an independent demountaole rim adapted to be fittedover the said fixed rim and provided with e series of bosses adapted tobe fitted within the sockets and means for securing the rims to gether.D

Other objects will appear and he hotter understood "from that embodimentof my invention of which the following is a specification,reterencebeing had to the accompanying drawings forming part thereof, inwhich, I I

Figure 1 is a. vertical sectional view of o. portion of myimprovedwheel. Fig. 2 is a side view of a portion of my wheel. Fig. 3 isa. detail perspective view of a portion of the demountable rim, and Fig.4 1S detail perspective View of a. portion of the fixed rim.

As shown in the drawings my improved wheel a is provided with a. fixedrim 5 having a series olsockets 6. and a demouutable rim 7 having aseries of bosses 8 which are fitted within the sockets and securedtherein,

by means of the bolts 9. The wheel a is similar in enerel structure towheel now 3.11 use, and has, its rim 5 corn nected with the hub b by thewire spokes or Thefixed rim 5 may he made otany suit nhle nmtei'ial andis provided with a series of radially disposed projections formingsockets 6 whichure in spaced relation with each other on the peripheryoi the fixed rim. These sockets are disposed inwardly toward'the centerof thewheel and are subetentinlly semi-circular in shame, and may thewirevirtue of having dctechn he of any depth suitshle to the-design. andcoi'istruction of the wheel. E37 referring to Fig. 4t it will henoted.thet the width of these sockets is not equal to the width cit therim, but are prete elly width eqnni to halt the width of t rim orapproximately so, thus :1 side Well it is orcvided against which thebosses 8 oi? the rim i" are adapted to contact when the go. is inposition upon the wheei. .The rim '5 also formed or? any materiel teenode. is provided with the usuni intern 7. flanges 11 on peripherythereoii for so curin a tire thereto. It is ohrious that thecircumference of the rim "a" is oi sudi cient size to be mounted on thelined rim 5,

and thus has provided on its 113F161 'goem ih cry the bosses 8 which arespace one each other so to he fitted in th incgiy sockets ti oi? th r ch tiel to the l operation of t. reel; we bosses are shaped so esto "othe shape ot the sockets 6, so ti the bosses are fitted snugly withinthesachets. the demountable rim wilt he securely heid to the fixed rim in a"rigid suhstontiei manner.

Thewidth. ot the bosses corresponds to the width of the sockets shown inl ig. 1: thus when demountahle rim mounted on the fixed rim. two memberscoi'ipcrate to form a solid rim structur and order to secure the twomembers her the bosses and side walls 10 of ti provided with. i ereilt'i i s; the t bores 12, for recc end. may he readily di srts for thepurpose 0 rim 7 from the rim 5 when desired.

lit is obvious that those skilled in may vary the details ofconstruction and arrangements of parts without (lemming; from the spiritoi my invention end there fore I do not wish to be limited to suchfeatures except as may. he required the claim. I
